There is no such thing as a static method in Objective-C; there are class methods and instance methods. Class methods are inherited just like instance methods.
Thus, when you say [NSMutableArray array], NSMutableArray's implementation of +array will be invoked (if it exists), regardless of whether or not said method is declared in the @interface of NSMutableArray.
